CAD Mini Viewer for Mac is a lightweight CAD drawing viewing and editing tool designed specifically for Apple computer users. It supports mainstream DWG/DXF file formats and features fast startup, simple operation, and a complete set of core functions, meeting users’ needs for viewing, measuring, annotating, and making simple modifications without installing large-scale CAD software.

I. Detailed Explanation of the Software’s Core Interface and Workspace

After launching the software, the main interface is divided into the following core areas:

Top Menu Bar and Toolbar: Contains entry points for all functions such as file operations, view controls, measurement, annotation, and layer management. The toolbar icons are intuitively designed and support customization.
Left Navigation Panel:
- Layer Management: Displays all layers in the drawing as a tree list, allowing you to control layer visibility, freeze/thaw, color, and more.
- Drawing Set/File List: When multiple drawings are open, switch between them in this area.
Central Drawing Area: The core area of the software, used to display and manipulate CAD drawings. Supports smooth zooming and panning.
Right-side Properties/Info Panel: When a graphic object (such as a line, circle, or text) is selected, its detailed properties are displayed here, such as length, radius, coordinates, layer, etc. Some properties can be edited directly.
Bottom Status Bar: Displays real-time information such as the current cursor coordinates, drawing scale, and layer status.

II. Complete Workflow: From Opening to Exporting

1. Create/Open a Project (Drawing)

Method 1: Open via Menu or Toolbar

Click the menu bar File -> Open..., or directly click the “Open” folder icon in the toolbar.
In the pop-up window, select the target DWG/DXF file and click “Open”.
Shortcut: Command (⌘) + O

Method 2: Open by Drag and Drop

Directly drag a CAD file from Mac Finder into the drawing area of the software’s main window to open it quickly.

Tip: The software supports opening multiple drawing files at the same time. Switch between them using the tabs at the top or the file list on the left.

2. Basic View Operations

After opening a drawing, you usually need to adjust the view to inspect details.

Zoom View:
- Scroll the mouse wheel up and down.
- Click the “magnifying glass” icon in the toolbar, or hold the Command (⌘) key while dragging the mouse in the drawing area.
- Shortcuts: Zoom in ⌘ + =, Zoom out ⌘ + -.
Pan View:
- Hold down the middle mouse button (scroll wheel) and drag. If there is no middle button, hold down the Spacebar while dragging with the left mouse button.
- Click the “hand” icon in the toolbar and then drag.
Fit to Window: Double-click the middle mouse button, or click the “Fit” icon in the toolbar, or use the shortcut ⌘ + 0.

3. Core Feature Applications: Measurement and Annotation

Measure Distance:

Click the “Measure” drop-down menu in the toolbar and select “Distance Measurement”.
Click the starting point in the drawing area, then click the endpoint.
The measurement results (horizontal distance, vertical distance, and total length) will be displayed in real time next to the cursor and in the information panel on the right.
Shortcuts: Usually customizable; there is no global shortcut by default. It is recommended to add frequently used measurement tools to the Quick Access Toolbar.

Add Text Annotation:

Click the “Annotate” or “Text” tool in the toolbar.
Single-click the position in the drawing area where you need to add text.
Enter the content in the pop-up text edit box, and you can adjust the font, size, and color in the properties panel on the right.
Click elsewhere in the drawing area to finish inputting.

4. Simple Editing and Layer Management

Selecting Objects: Click to select a single object, hold the Shift key and click to add to the selection. Drag the mouse to perform a box selection.
Deleting Objects: After selecting an object, press the Delete key.
Controlling Layer Visibility: In the layer management panel on the left, click the “eye” icon in front of a layer name to toggle the display of that layer. This is crucial for viewing specific parts of complex drawings.

5. Final Export and Sharing

Export as PDF or Image:

Click the menu bar File -> Export As....
Select the export format (e.g., PDF, PNG, JPG).
Set the export range (current view or full drawing), resolution, and other parameters.
Choose the save path and click “Export”.
Shortcut: ⌘ + E (may be for printing or exporting, refer to the software menu for specifics).

Printing Drawings:

Click the menu bar File -> Print..., or use the shortcut ⌘ + P.
In the print settings dialog, set the paper size, orientation, print range (window/full drawing), and scale.
After previewing to confirm everything is correct, connect to a printer and print.

III. Advanced Tips for Common Features

Quickly locate views: In large drawings, you can first hide irrelevant layers, then use the “Window Zoom” feature (the toolbar icon is usually a magnifying glass with a rectangular frame) to box-select the area you need to examine in detail.
Tips for measuring area: When using the “Area Measure” tool, for irregular shapes, you can click multiple points in succession to enclose a closed region, and the software will automatically calculate the perimeter and area. For closed polylines, simply select the object, and its area information is usually displayed in the properties panel on the right.
Permanence and temporariness of annotations: Annotations added by the software (such as text and clouds) are saved in the original drawing by default. If you want annotations to be used only for temporary viewing without modifying the original file, you can use the “Snapshot” or “Markup” feature (if provided by the software), or add annotations on a separately created layer and choose to turn off that layer before sharing.
Custom shortcuts: Some versions support custom shortcuts. Go to Settings or Preferences -> Shortcuts to assign convenient key combinations to frequently used operations (such as measuring and toggling layers).

IV. Common Problems and Solutions

Symptom	Possible Cause	Solution
After opening the drawing, it appears blank or some graphics are missing	1. The drawing version is too high or uses special objects. 2. The relevant layers are turned off or frozen.	1. Try asking the file provider to save it as a lower version (such as AutoCAD 2010 DWG format). 2. Check the layer management panel on the left to ensure all layers are turned on (eye icon visible) and unfrozen.
The software runs slowly and operations are not smooth	1. The opened drawing file is too large or too complex. 2. The Mac hardware configuration is relatively low.	1. Turn off unnecessary layers to reduce the content displayed on screen. 2. Try using the “Regenerate” (Regen) feature (usually in the View menu). 3. Make sure to close other programs that consume a large amount of resources.
Unable to select or edit certain graphics	1. The graphics are on a locked or frozen layer. 2. The graphics are “blocks” or part of an external reference.	1. Check and unlock or unfreeze the corresponding layer. 2. Use the “Explode” tool (if provided by the software) to try exploding the block, but operate with caution as it may affect the drawing structure.
Incorrect dimensions when printing or exporting	Incorrect scale setting when printing/exporting.	In the “Scale” setting of the print or export dialog box, select “Scale to fit drawing space” or set it to a specific scale (such as 1:100). Before printing, be sure to use the software’s measurement tool to verify a known dimension on the drawing.
Text displays as garbled characters or question marks	The drawing uses fonts that are not installed on the Mac system.	1. Try specifying font substitution rules in the software settings, using existing system fonts (such as Songti and Heiti) to replace missing fonts. 2. Contact the drawing creator to obtain the font files used and install them into the Mac’s Font Book.
